Study links romantic rejection with reward and addiction centers in the brain

07.07.2010
Researchers have linked rejection by a romantic partner to brain activity associated with motivation, reward and addiction cravings, according to a study published in the July issue of the Journal of Neurophysiology.

Lucy Brown, Ph.D., clinical professor in the Saul R. Korey Department of Neurology and of neuroscience at Albert Einstein College of Medicine of Yeshiva University, is the corresponding author of the study. This is the third publication in which Dr. Brown and her research group demonstrated that primitive reward and survival systems are activated in people who look at their beloved.

Using functional magnetic resonance imaging (fMRI), researchers recorded the brain activity of 15 college-age adults who had recently been rejected by their partners but reported that they were still intensely "in love." Upon viewing photographs of their former partners, several key areas of participants' brains were activated, including the ventral tegmental area, which controls motivation and reward and is known to be involved in feelings of romantic love; the nucleus accumbens and orbitofrontal/prefrontal cortex, which are associated with craving and addiction, specifically the dopaminergic reward system evident in cocaine addiction; and the insular cortex and the anterior cingulate, which are associated with physical pain and distress.

By tying these specific areas of the brain to romantic rejection, the research provides insight into the anguished feelings that can accompany a break-up, as well as the extreme behaviors that can occur as a result, such as stalking, homicide and suicide.

"Romantic love, under both happy and unhappy circumstances, may be a 'natural' addiction," said Dr. Brown. "Our findings suggest that the pain of romantic rejection may be a necessary part of life that nature built into our anatomy and physiology. A natural recovery, to pair up with someone else, is in our physiology, too."

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
